osc-clj 0.5.0 - Open Sound Control for Clojure
Hi there, I just thought I'd announce quite a significant update to osc-clj. This is the first release that can claim to have full support for the OSC spec: http://opensoundcontrol.org/spec-1_0 The major new features are as follows: * Support for the timely dispatch of bundles scheduled for the future (using at-at) * Full support for OSC pattern matching (allowing incoming messages to match against multiple handler 'methods' * Support for zeroconf - when you create a server, you can pass a string as an optional param which will be automatically registered with zeroconf when you explicitly turn it on with (zero-conf-on). So, if you're interested with working with new-school instruments/interfaces such as TouchOSC, grab a copy of osc-clj and happy hacking! https://github.com/overtone/osc-clj/ Sam --- http://sam.aaron.name -- You received this message because you are subscribed to the Google Groups Clojure group.

Spitting out a lazy seq to file???

Re: Stanford AI Class
The Machine Learning class from 2008 has been available at iTunes University for a while, but I'm not aware of it having the same kinds of support materials as the online AI class has said they will offer. Be forewarned: the Machine Learning class is presented in a very math intensive way (statistics, linear algebra, and multivariate calculus), and a lot of the math refreshers were apparently offered in sessions with TAs that were not (as far as I know) placed online. I felt like I got a greater understanding of machine learning by reading the book Data Mining by Witten. -- You received this message because you are subscribed to the Google Groups Clojure group.

And how? Thanks in advance!!! spit operates on strings, so therefore you have to turn your data into one big string first. (spit implicitly calls str on its argument, but this is not very useful.) What you have is a sequence of string, so depending of what you want to appear in the file you have multiple options: For an arbitrary clojure data structure you can use pr-str to convert it into the same format you get at the repl: (spit output.txt (pr-str (map change-line old-data))). This can be useful to dump some data to a file and will yield something like this: (line1 added stuff line2 added stuff) To simply write a file where each line corresponds to a string element in the sequence, you can either build a new string with consisting of the strings of the seq, each with a newline character appended to the end, concatenated together and spit that, or you can use something else that doesn't require you to build this monolithic string. Since you used line-seq rather than slurp to read in the file, I will instead demonstrate an other approach than spit: (require '[clojure.java.io :as io]) (with-open [in (io/reader input-filename) out (io/writer output-filename)] (binding [*out* out] (- in (line-seq) (map change-line) (map println) (dorun This consumes the sequence line by line and writes the lines to the file. This solution only needs to have one line in memory at a time. The spit approach would require one big string to be constructed, and might not be very suited for big files. The code would output a file like this: line1 added stuff line2 added stuff So in general, use slurp together with spit or read-line (or its line-seq variant) together with println. // raek -- You received this message because you are subscribed to the Google Groups Clojure group.

Clojure/conj for beginners?
Hi Recently I've taken interest to learning Clojure. I've watched presentations, read the Joy of Clojure, done some examples on 4clojure, but have yet to do any real programming. I work in enterprise-land and for the most part its all Java without much room to try newer things. With that being said, I do have some company money dedicated to professional development. Unfortunately its not enough for the training option at Clojure/conj, but would be enough for travel and conference attendance. I was wondering if the conference would be useful for someone in my position, a Clojure beginner. Would the presentations be over my head, or worthwhile?

Re: syntax quoting and namespaces misbehaving in test?
I *think* it is expected behavior.

Re: syntax quoting and namespaces misbehaving in test?
100% expected. Try (def other.ns/some-var 1) - the compiler tells you it's illegal. If you read the compiler source, it's looking at the var's namespace and refusing to def it if it's not the current namespace. If you want behavior like this, you want (intern), not (def).

But if you want to have the program find that out, then there would be no point in having a fitness function that already contains the solution. Hmmm. Clojure has immutable data structures.

Re: Stanford AI Class
On Aug 12, 10:25 pm, daly d...@axiom-developer.org wrote: Consing up a new function and using eval is certainly possible but then you are essentially just working with an interpreter on the data. This is the same in CL. When you have a GP system that constructs new program trees then inside your fitness function you will eval it. Clojure does not come with an interpreter, so eval results in a compiled program that gets executed. You can of course use recombination and mutation of programs and/or subprograms and thus create a new generation that is now modified, which then gets its fitness measured. How does function invocation actually work in Clojure? Lisp-1. This is much better suited for a (predominantly) functional programming style. Also see this paper by Kent Pitman: http://www.nhplace.com/kent/Papers/Technical-Issues.html (“Probably a programmer who frequently passes functions as arguments or who uses passed arguments functionally finds Lisp1 syntax easier to read than Lisp2 syntax;”) In Common Lisp you fetch the function slot of the symbol and execute it. To modify a function you can (compile (modify-the-source fn)). This will change the function slot of the symbol so it will execute the new version of itself next time. Does anyone know the equivalent in Clojure? Would you have to invoke javac on a file and reload it? The Clojure compile function only seems to know about files, not in-memory objects. In Clojure it is: (eval (modify-the-source fn)). -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: defining tests for an api to be called by the implementations
actually this isn't as bad as I thought. things work more or less as expected, I can blocke the tests with the test-ns-hook and run them in other namespaces as expected... the reason things ran in my repl but would not compile outside is that there were some missing test dependencies that were in scope in the pom running my repl, but not in the one running the test. lesson learned.

I have a testing routine with a bunch of functions that each call a function to get a clean instance of an implementation, initializes it with some data and then interrogate it. with the exception of calling (new-foo) or (new-bar), foo and bar can be tested identically. I would like to be able to define tests in a namespace for the api, then have a test-foo namespace that calls those tests with *new-test-instance* bound to new-foo. likewise for new bar. because I would like the exact same tests run, the whole point is these things should behave the same at the API level. I don't want to have to copy and paste all my tests and make sure I keep them synchronized, that seems like an error waiting to happen. I can define the tests in test-api with deftest but doing so will cause the test to be run there (when I call mvn clojure:test), and as there is no implementation they will of course fail. I can block test- api from calling it's tests with: (defn test-ns-hook []) but then the tests become a pain to call from another namespace. surely there is a way to do this? (defn test-ns-hook [] (when (bound? #'api-instance) ...))? in test-api with the blocking test-ns-hook, I tried (def the-tests [ (deftest test-1 ) ]) then in test-foo I tried (defn test-ns-hook [] (dorun (map (fn [x] (binding [project.test-api/*new-test-instance* (fn [] (new-foo))] (x))) project.test-api/the-tests))) that doesn't work I keep seeing this: Uncaught exception, not in assertion. expected: nil actual: java.lang.NoClassDefFoundError: org/slf4j/impl/ StaticLoggerBinder ... except if I put that exact same test-ns-hook implementation into the repl and call (run-tests) everything checks out *exactly* as expected.

Re: Clojure for Android
I'd consider taking this. I've worked a little bit behind the scenes to get Clojure to run better for me personally on android. Recently, I've been working to get ClojureScript to work well for SL4A (Scripting Layer for Android). I wanted to try to get a native Clojure package working for SL4A, but given that the above works pretty well, I need some sort of real motivation to continue the work.
